Fix spam error message when setting energy_performance_preference

The 'intel_pstate' driver does not allow the EPP to be set to anything
but 'performance', previously auto-cpufreq tried to set this to
'balance-performance' which caused a spam of write error messages in
journalctl and also the 'balance-performance' preference was ignored.
This commit just changes the 'balance-performance' preference to
'performance'.
